Answer 1

Speech jamming is actually best done with about 200ms of delay in adults. Shorter times are more likely to be processed as echo and discarded, longer times (like a few seconds) don’t match up closely enough to trigger the reflex that subconsciously monitors your speech and compensates for/corrects errors without you thinking about it. 200ms is long enough so that the sound at your ear is different than at your mouth, and so the brain processes that as an error.

Pro tip: if you’re working an event and a rowdy guest crashes the party and takes the mic unwanted, throw 200ms onto that feed.
